John McCarthy's two fall semester sections of Calculus I will be instructed by other professors in MSU's Math Department "indefinitely," spokesperson Jason Cody said.

McCarthy, 57, reportedly shouted about Steve Jobs, God, religion and other topics during one of his classes Monday afternoon, then stripped naked and continued screaming in the Engineering Building's hallway in what students called an apparent mental breakdown.

Witnesses took to social media, posting numerous first-hand accounts of the incident around the Internet, putting the incident in national headlines.

MSU police placed McCarthy in protected custody and transported him to a local hospital. He will not be charged with a crime, according to police.

Cody said MSU has taken not taken personnel action against McCarthy as of Monday. The matter will be addressed at a later date, he said.
